ELECTRICALLY-HEATED SOLDERING-MAOHINE.

To all whom it may cone m:

llc it: known that i, Iilon'rcoaiinir H. Johnson, of Utica, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Electrically-Heated bloldering-Machines and I do hereby declare that the following is=a full, clear and exact. description thereof, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference.inarkcd-thereon, which form part ot'v this specification.

The object of my present invention is to provide a soldering; machine adapted for use on cans, having rotary electrically.heatcdsoldering irons of improved and simplitied construction and arrangement, and which isetlicient and adapted to withstand ivear' substantially free from liability. to get out of orde* and readily assembled and dismantled. ltigure 1 shows a partial side elevation of a machine.eii-ibodying the features of my present improvement. Fig. 2 shows apartial cross-sectional view of the inacl'iine. ltig. 3. is-an enlarged detail sectional view otihe soldering iron with its appurtenances. l lig. 4- is a plan view oi certain parts and I .by line ..\-ll thesection on which Fig. ills taken.

lathi'ough the medium of the bar ll, there is provided on the shaft 21 a cam which isconnected by conncctin rod 23 with the bai'-l .-l,.so that as the shaft- 21 revolves and the spindles Lfi'are revolved, they will be raised and lowered. in raising and lowering the, spindle, Mi slide through'the bean ings I). The spindles are provided at their lower ends with clamps :25 by means oi which the soldering irons are attached ll) the machine. v

-Tl19 soldering irons consist of a tubular shank 26 having a. tubular body 52? secured on the lower end, this body teriiiinaiing at the lower end in acircular operative eth c or face The body, 27 is reduced above the lower end atl ording a. shoulder :39, and

above the shoulder the body is incloscd in a its uppersend, and. these flanges are screwthreaded at their edges to engage with suitable screw thr ads in the shells, Within the case 30 there is provided an electrical heating coil 31' supported ina suitable mass oi insulating matter, and the terminals of this coil 31 are indicated by 31 and ill and are carried out, through the upper end of the. case. Secured on the upper end of the case 30 is a disk 32 ofiiisulating material, as, for instance, slate. This dish is substantiall a washer perforated to provide a passage. for the shank 26- On the. upper face of the disk 32 are mounted two terminal contact rings and 34. The outer ring 33 isconnected with one end, ail-31, of the, heating coil.

, while the-inner contact ring 3% is connected with the Ot-l"ltl1;011(l of the heatingcoil.

Surmounting the disk 32 is another disk 35 of insulating material and similar constri'ict-ion, which has secured to it on the underside the outer and inner contact rings 35,6 and37 respectively. These rings correspond in diameter and location with the rin- 's 3 5 and 2-H reswctivclv, so that when 1 assembled the edges of the rims en' 'a e each :3 9 23 i Oll)(l.liS shown.v .lhc electric contact ringv the upperend of therertical shaft 18." The are protected by a cap 38 having a dependingil'langewhich is insulated with reference to tliecontacts.

. lloavoid dependin on the bearing of the disk 35 on the spindle 26 to maintain the trio li hts and fixture D (3 f the k 1 I 4 GlPCtX. cm conon, ed cutthrough top of .i will be continued i cord or cable -10 for a sutlicient length adapt than to reach the outlet b d2 provided on the frame, which outlet box will prefeatuy be provided with an ordinary electrical socket, while the end of the conductors 4 .0 and all will be provided with the ordinary plug used in connection with elec' Electric conductors will be brought to the several outlet boxes 1-2, which may be provided on the machine through a conduit as 43 supported on the frame of the m him. The cables 40 are of sutlicient length and flexibility to permit the soldering irons to have the desired movement up and down vertically. Each pair of insulating disks 35 will prefer ably be coupled together a bar 00 which will serve to hold the insulating disks 35 together with their contact rings against rotation in connection With the soldering iron and the other parts moving therewith. An axial opening through the soldering iron, its shank 26 and the spindle l provided to I'QCQlXG a push rod d5 provided with a weight at its upper end. The push rod rests on the can cap to maintain the same in position when the operative edge 28 of the soldering iron is lifted from the can.

It is evident that when electric current isfsupplied through conductors and il,

that through the medium of the contact rings 1 the circuit will be completed through the heating coil 30 effectively and with certainty, while permitting the soldering iron, the heat- .ing coil and its appurtenances to be rotated, and while also permitting the soldering iron to have the vertical movement which is necessary in this class of machine.

When in the operation of the machine the soldering iron descends, it operates upon the cap provided on the head of the can supported on the table of the machine in the well known manner.

It is evident that the current Will be supplied to the heating coil of the soldering iron in a simple and efiiclent manner by the construction herein described, and'that in case of trouble an iron can. be readily removed from the machine and the heater and its uppurtenances removed and replaced Without trouble and with despatch by an ordinary machine operative. This may occur occasionally or frequently from trouble with the soldering iron and the metal adhering to its face, or from trouble with the heating coil, or from various troubles which beset devices of this character. It will also be noted that each soldering iron quite independent from its neighbors in the machine and can be retact base supported on the top of the case and carrying contact for said collector rings respectively, substantially as set forth.

2. The combination in a soldering machine of a rotary soldering iron, a case mounted on and inclosing the body of the iron, a heating coil in the case, insulated collector rings mounted on the end of the case to which the 8 ends of the coil are respectively connected, non-rotatable contact pieces engaging with the collector rings and flexible connections with said contact pieces, substantially as set forth.

3. The combination in a soldering machine of a spindle, a rotary soldering iron mounted thereon in suspended position, a case inclosing the body of the iron, a heating coil in the coils are respectively connected mounted on the case at different distances from the center of rotation of said soldering iron, other contact pieces held against rotary movement, and electrical conductors connected with said 1 latter contact pieces, substantially as set forth.

l. In a soldering machine the combination of a spindle, rotary soldering iron suspended thereon, a case inclosing the body of the 1 iron, a heating coil mounted in the case, collector rings supported from the case and surrounding the spindle in circles of different radii and to which the ends of the coils are respectively connected, other non-rotatable 1 rings surrounding the spindle and engagin with said collector rings respectively, an electric conductors connecting with saidlatter rings respectively, substantially as set forth.

In a soldering iron having a cylindrical body, a cylindrical case conslsting of two shellcylinders oflarger and smaller diameters respectively, the former having an inwardly pro ecting flange at one end and't-he' latter having an outwardly projecting flange at the other end, a heating coil provided In the case, and means for m g electrical connection with the ends of he coil res ectively through the exterior of the cylindrical which the ends of the calls are respectively connected n'munted mid encircling the spindie and being of larger 11ml smaller dinmw 'iieis respectively, mid non-nitziambie contacts wig-"aging with said Contact pieces respeci'ively, substmitialiy as $01; forth.
